Trace Model 050

Trace Model 050: H2S Detection

The Trace 050 series of H2S analyzers combines functionality, ease of use, and portability all into one package. Need to collect readings from several locations? If so, then this is the perfect instrument for your needs.

The Model 50 may also be used as an online process analyzer.


Battery Power

The Trace 050 model line of analyzers can be supplied with an optional battery power supply to complete remote operation. This feature is available on the 100 model line also! An integrated charger will return the battery to full storage during an overnight charge. A fully charged battery will allow the analyzer to operate from eight to sixteen hours.

4-20 mA Loop output

4-20 mA Loop output for remote monitoring

Data Communication

Modbus RTU on RS232 or RS485


SMARTalk connects to the Data Communication option to provide visibility and remote operation via personal computer or host with true bidirectional communication. The operator does not have to travel to the measurement site to alter operation, initiate calibration, or view data. Controls, reports, and data are available at lab or office via a personal computer link. Remote access reduces the chance of "no fault found" service calls where on site trips find no fault with the equipment.


Allows data to be transferred from the analyzer to a PC using a memory module.

LCD Graph Display

The display is a paperless chart recording of the concentration with selectable time scale to make comparisons and graphically display operating trends over time.

Back-lighted Display

A new option available on the TRACE analyzer is a light behind the LCD to make operation even more user friendly.

Sample Pump

A miniature DC powered rotary vein pump to provide sample flow from atmospheric sources. This option is necessary if there is no line pressure.

Liquid Block Filter

Prevent liquids from entering the analyzer.

Electronic Flow Meter

Signals when the flow is +/- 30% of optimal.

Diagnostic Alarm

Signals when there is a functional problem with the analyzer.

Concentration Alarm

Signals when the reading is above a user set value.
